Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic air cleaner for collecting dust in the air by a mist generated by ultrasonic waves.

[0002]

2. Description of the Related Art Generally, an air purifier is one in which air is forced to pass through a filter such as cloth, or sucked air is passed through a positively or negatively charged grid to positively remove dust. Alternatively, it is also known that after being negatively charged, dust is adsorbed by passing through a negatively or positively charged grid.

[0003]

However, in the air purifier configured as described above, the former requires frequent replacement of the filter, which is troublesome, and the latter requires a high grid. Since it has to be applied with a voltage to charge dust, it has a drawback that the structure is complicated and the cost is high.

According to the present invention, a duct is provided with a suction fan provided with a suction fan for sucking clean air into a duct, and a container connected to the duct is filled with a liquid. A first ultrasonic transducer is mounted, and a mist generating section that generates mist by the ultrasonic waves from the ultrasonic transducer, and a second ultrasonic transducer mounted in an intermediate duct communicating with the container. An ultrasonic condensing unit that generates strong ultrasonic waves, an air blowing port that communicates with the intermediate duct, and a water droplet collecting unit including a water collecting port and a collecting container connected in the vicinity of the air blowing port. Mixing the air from the air suction unit into the mist generated in the mist generation unit to attach dust in the air to the mist, and to generate a strong ultrasonic wave from the second ultrasonic transducer of the ultrasonic condensing unit. By the sound wave, the dust Together with the mist is condensed to water droplets, water droplets were collected in the collection vessel from the water droplet collection port of the water droplet collecting portion is intended for blowing clean air from the air outlet.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the water supplied to the container of the mist generating section is atomized by the first ultrasonic vibrator, and the air sucked from the air suction section is applied to the atomized water mist. When sprayed and mixed, the dust contained in the air is captured by the mist, and when the captured mist is irradiated with powerful ultrasonic waves, the mist collects and becomes a water droplet, and along with the dust is deposited on the wall around the duct. Only the air that has been condensed by dew condensation or dropped and captured, dust removed, and purified is blown out from the air outlet.

FIG. 1 is a schematic configuration diagram of an ultrasonic air cleaner according to an embodiment of the present invention. A suction fan 2 is attached to a suction port 1a of a duct 1 and a container 3 is connected to the duct 1 in a hermetically sealed state. Then, a liquid 4 such as water is supplied to the container 3 by a pump 5 in a constant amount, and an ultrasonic transducer 6 is supplied to the container 3.
Is attached, and the oscillation output is supplied from the oscillator 7 to the first ultrasonic transducer 6.

A second ultrasonic oscillator 8 for generating a strong ultrasonic wave is attached to the intermediate duct 1b after the container 3, and the second ultrasonic oscillator 8 is supplied with an oscillation output from an oscillator 7. Further, a water droplet recovery port 1d and a recovery container 9 are mounted in the vicinity of the blowout port 1c of the duct 1.

In the ultrasonic air cleaner of this embodiment having the above-described structure, first, water is appropriately supplied to the container 3 by the pump 5, and the first ultrasonic vibrator 6 attached to the container 3 The ultrasonic oscillator 8 is driven by the output of the oscillator 7 to generate mist in the upper part of the container 3, and the output of the oscillator 7 drives the second ultrasonic oscillator 8 mounted on the intermediate duct 1b. When a suction fan 2 is driven there, the air sucked from the suction port 1a of the duct 1 is mixed with the mist generated in the container 3, and the dust contained in the air is mist. Attached to the intermediate duct 1
b.

Here, the mist is condensed by being vibrated by the strong ultrasonic waves generated by the second ultrasonic vibrator and drops into water droplets, and dust attached to the water droplets at this time is also dropped together with the water droplets. Because it falls, blowout port 1
The air blown out from c contains almost no dust, purified air is blown out, and the condensed water droplets are collected in the collection container 9 from the water droplet collection port 1d and drained from the drain port 10.

According to the present invention, the dust in the air is adhered to the mist by mixing the mist with the sucked air, and the mist is vibrated by a strong ultrasonic wave so as to be dropped as a water drop. Dust can be separated from the air, and only purified air can be blown out from the blowout port 1c, and negative ions are generated by the strong ultrasonic waves, whereby the air can be sterilized.

FIG. 2 is a block diagram of an ultrasonic air cleaner according to another embodiment of the present invention, in which 1 is a duct, 1a is a suction port, 1b is an intermediate duct, 1c is a blowing port, 1d is a water droplet collecting port, Two
Is a suction fan, 3 is a container, 4 is a liquid, 5 is a pump, 6 is a first ultrasonic oscillator, 7 is an oscillator, 8 is a second ultrasonic oscillator, and 9 is a recovery container. Since it is the same as the above-mentioned embodiment, description thereof will be omitted, but in the present embodiment,
A grid member 10 is vertically mounted on the intermediate duct 1b so that water droplets condensed by strong ultrasonic waves hit the grid 10 and easily drop.

In the ultrasonic air cleaner of this embodiment having the above-mentioned structure, the mist mixed with air is condensed into water droplets by vibrating with strong ultrasonic waves, and the water droplets collide with the lattice 10. Since it is easily attached to the lattice 10, the air blown out from the blowout port 1c has a feature that it does not contain mist at all.

In the above embodiment, the grid member 10 is vertically mounted on the intermediate duct 1b.
If 0 is mounted sideways and the interval between the lattice members 10 is narrowed,
Similarly, the mist is likely to be condensed into water droplets, and the air blown out from the outlet 1c does not contain mist at all.

Further, the water recovered in the recovery container 9 is passed through a filter to remove dust and then transferred to another container, and is supplied to the container 3 by the pump 5, whereby the water is circulated to reduce water consumption. can do.

As is apparent from the above description, in the ultrasonic bottom air cleaner of the present invention, the air sucked from the suction port is mixed with the mist generated by the ultrasonic vibrator, and the dust contained in the air is mixed. Is attached to the mist, and when the mist is condensed and collected, it is condensed and collected together with the dust.Therefore, the air blown out from the air outlet contains almost no dust, and the strong ultrasonic waves cause a negative impact. Ions of
This has the advantage that air is sterilized.
